Here is a new utility to patch the EFI firmware in VMware Workstation and Fusion to allow the non-server versions of Mac OS X 10.5 (Leopard) and 10.6 (Snow Leopard) to run. Yoiu will need macOS unlocker 3 if you are using Workstation on non-Apple hardware. I still have to find a way to do this on ESXi as the UEFIPatch utility will not run in the ESXi console.
This currently supports:

Workstation 11/12/14/15 on Windows and Linux
Workstation Player 7/12/14/15 on Windows and Linux﻿
Fusion 10/11 on macOS
